A communication hole 116 is formed in the center of the opposing surface 211 . A plurality of guide grooves 210 are formed on the opposing surface 211 and connected to the communication hole 116 and extending spirally from the communication hole 116 toward the outer periphery. The material supplied to the groove 202 of the flat screw 111 is melted between the flat screw 111 and the barrel 112 by the rotation of the flat screw 111 and heating by the heater 113, and is melted between the groove 202 and the guide by the rotation of the flat screw 111. It flows along the groove 210 and is guided to the central part 205 of the flat screw 111. The material flowing into the central portion 205 is guided to the injection control mechanism 120 through a communication hole 116 provided at the center of the barrel 112.

The injection control mechanism 120 includes an injection cylinder 121, a plunger 122, and a plunger drive section 123. The injection control mechanism 120 has a function of injecting the molten material in the injection cylinder 121 into the cavity 117, which will be described later. Injection control mechanism 120 controls the amount of molten material injected from nozzle 114 under the control of controller 50 . The injection cylinder 121 is a substantially cylindrical member connected to the communication hole 116 of the barrel 112, and includes a plunger 122 inside. The plunger 122 slides inside the injection cylinder 121 and pumps the molten material in the injection cylinder 121 to a nozzle 114 provided in the plasticizing device 110. The plunger 122 is driven by a plunger drive section 123 that includes a motor.

The mold 12 includes a movable mold 12M and a fixed mold 12S. The movable mold 12M and the fixed mold 12S are provided facing each other, and have a cavity 117 between them, which is a space corresponding to the shape of the molded product. A molten material is pumped into the cavity 117 by an injection control mechanism 120 and is injected from the nozzle 114 .

The mold clamping device 130 includes a mold drive section 131 and has a function of opening and closing the movable mold 12M and the fixed mold 12S. Under the control of the controller 50, the mold clamping device 130 rotates the ball screw 132 by driving a mold drive section 131 constituted by a motor, and moves the movable mold 12M coupled to the ball screw 132 with respect to the fixed mold 12S. The mold 12 is moved to open and close. That is, the fixed mold 12S is stationary in the injection molding system 100, and the mold 12 is opened and closed by moving the movable mold 12M relative to the stationary fixed mold 12S.

The movable mold 12M is provided with an extrusion mechanism 407 for releasing the molded product from the mold 12. The extrusion mechanism 407 includes an ejector pin 408, a support plate 409, a support rod 410, a spring 411, an extrusion plate 412, and a thrust bearing 413.

The support plate 409 is a plate member that supports the ejector pin 408. Ejector pin 408 is fixed to support plate 409. The support rod 410 is fixed to the support plate 409, and is inserted into a through hole formed in the movable mold 12M. The spring 411 is arranged in a space between the movable mold 12M and the support plate 409, and inserted into the support rod 410. The spring 411 urges the support plate 409 so that the head of the ejector pin 408 forms part of the wall surface of the cavity 117 during molding. The extrusion plate 412 is fixed to the support plate 409. The thrust bearing 413 is attached to the extrusion plate 412 so that the head of the ball screw 132 does not damage the extrusion plate 412. Note that instead of the thrust bearing 413, a thrust sliding bearing or the like may be used.

FIG. 9 is an explanatory diagram showing the movement of the mold 12. When the mold clamping device 130 shown in FIG. 6 drives the ball screw 132 to move the movable mold 12M relative to the fixed mold 12S by a predetermined amount d in the +Y direction as shown in FIG. The end on the Y direction side contacts the thrust bearing 413, and the ejector pin 408 no longer moves in the +Y direction. In this state, when the movable mold 12M is further moved in the +Y direction, only the movable mold 12M moves in the +Y direction with the ejector pin 408 in contact with the molded product MD, so that the ejector pin 408 moves inside the cavity 117. The molded product MD is relatively extruded, and the molded product MD is released from the movable mold 12M. That is, in this embodiment, the molded product MD is released from the movable mold 12M at a stationary position without moving the ejector pin 408 itself to make it protrude. The robot 60 takes out the molded product MD thus released from the injection molding machine 10.

According to the injection molding system 100 of this embodiment described above, not only the injection molding machine 10 but also the material supply device 20 necessary for operating the injection molding machine 10, the temperature controller 40, the dryer 30, The controllers 50 are all arranged in one housing 90, and the housing 90 is configured to be movable by casters 99. Therefore, the injection molding machine 10 can be freely moved and used within a facility such as a factory, and restrictions on the locations where the injection molding machine 10 can be used can be suppressed.

Further, according to the present embodiment, the robot 60 that takes out the molded product from the mold 12, the inspection device 70 that inspects the molded product, and the tray 81 on which the molded product is placed are moved to the takeout position where they can be taken out from the outside. A moving mechanism 80 is further provided inside the housing 90. Therefore, each device used in a post-process after injection molding is arranged within the housing 90, and the convenience of the injection molding system 100 can be improved.

Furthermore, in the present embodiment, a first base 91, a second base 92, and a third base 93 are provided inside the housing 90, and include an injection molding machine 10, a robot 60, and an inspection device. 70 and the moving mechanism 80 are arranged on the first base 91, the controller 50 is arranged on the second base 92, and the material supply device 20, the temperature controller 40, and the dryer 30 are arranged on the third base. It is arranged on a stand 93. Therefore, each device can be efficiently arranged within the casing 90 while separating the controller 50 from heat sources such as the injection molding machine 10, the dryer 30, and the temperature controller 40.

Further, in the present embodiment, the first base 91 includes an upper section 91t and a lower section 91b, and the moving mechanism 80 is arranged in the lower section 91b. When the housing 90 is viewed from above, at least one of the injection molding machine 10, the robot 60, and the inspection device 70 is arranged in the upper part 91t so as to overlap a part of the moving mechanism 80. has been done. Therefore, the size of the injection molding system 100 in the horizontal direction can be made compact while expanding the operating range of the moving mechanism 80.

Further, in this embodiment, when the housing 90 is viewed from above, the inspection device 70, the injection molding machine 10, and the robot 60 are arranged in the housing 90 in this order clockwise or counterclockwise. There is. Therefore, the molded product can be efficiently transported by the robot 60 between the injection molding machine 10 and the inspection device 70.

Further, in this embodiment, when the housing 90 is viewed from above, the arrangement area where the inspection device 70, the injection molding machine 10, and the robot 60 are arranged and the position at which the molded product is taken out do not overlap. Therefore, it is possible to suppress the user's operation of taking out the molded product from affecting the operation of the robot 60.

Further, in this embodiment, the material supply device 20 includes a compressed air pump 22 that generates compressed air, and supplies the material to the injection molding machine 10 using the compressed air. Therefore, the injection molding system can be operated without receiving compressed air supply from factory equipment. As a result, the degree of freedom in installing the injection molding system 100 can be increased. Furthermore, in this embodiment, the temperature controller 40 adjusts the temperature by circulating a heat medium between it and the mold 12, so there is no need to receive water supply from factory equipment. Therefore, the degree of freedom in installing the injection molding system 100 can be further increased.

Furthermore, in this embodiment, the ejector pin 408 protrudes from the movable mold 12M toward the fixed mold 12S by moving the movable mold 12M relative to the fixed mold 12S, rather than moving the ejector pin 408 itself. On the other hand, in the comparative example shown in FIG. 10, after moving the movable mold 12M relative to the fixed mold 12S by a predetermined amount d in the +Y direction, the movable mold 12M is stopped, and the ejector pin 408 is moved to - It is being moved in the Y direction. Therefore, as the ejector pin 408 moves, the molded product MD also moves, and the distance between the fixed mold 12S and the molded product MD becomes a distance d2 smaller than the moving distance d of the movable mold 12M. In other words, when the ejector pin 408 itself is moved, the possibility that the position at which the molded product MD is released from the mold changes every molding increases. However, in this embodiment, as described above, the mold release is performed by moving the movable mold 12M instead of the ejector pin 408, so the molded product MD is removed from the movable mold 12M without changing the position of the molded product MD. It can be released from the mold. Therefore, the molded product can be taken out by the robot 60 with high accuracy.

Moreover, in this embodiment, since the material is melted using the flat screw 111, the injection molding machine 10 can be downsized. Therefore, the injection molding system 100 can be configured compactly.
